MP8756 26V, 6A, Low I , High-Current, Q Synchronous, Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP8756 is a fully integrated, high- Wide 4.5V to 26V Operating Input Range frequency, synchronous, rectified, step-down, Output Adjustable from 0.6V switch-mode converter. It offers a very compact Ultrasonic Mode (USM) solution that achieves 6A of continuous output 117 A Low Quiescent Current current with excellent load and line regulation 6A Continous Output Current over a wide input supply range. Adaptive COT for Fast Transient DC Auto-Tune Loop The MP8756 operates with high efficiency over a wide output-current load range based on Stable with POSCAP and Ceramic Output MPS proprietary switching loss reduction 1% Reference Voltage technique and internal low R power DS(ON) Internal Soft Start MOSFETs. Output Discharge 700kHz Switching Frequency Adaptive constant-on-time (COT) control mode OCP, OVP, UVP (Hiccup), and Thermal provides fast transient response and eases loop Shutdown stabilization. The DC auto-tune loop provides Available in a QFN-12 (2mmx3mm) good load and line regulation. Package Full protection features include over-current limit, over-voltage protection (OVP), under-voltage APPLICATIONS protection (UVP), and thermal shutdown. Laptop Computer The converter requires a minimum number of Tablet PC external components and is available in a QFN- Networking Systems 12 (2mmx3mm) package.
